well I have been experiencing a crazy water leak for several weeks. Finally traced it down to inside A post near windshield corner. (had windshield replaced a little over a year ago so called to get it repaired under warranty) guy pulls the windshield and low and behold there are 2 cracks in the pinch weld in the corners one on each side of A pillars under the windshield! Any guys with overhead water leaks may have similar cracks. Only bad thing is it is under the windshield and can only be detected by removing the windshield. Just wanted to pass this along. hopefully the patch we did will hold but time will tell...
